What is the primary function of a fetal scaler electrode?

The primary function of a fetal scaler electrode is to convert Fetal Electrocardiogram (FECG) signals into a fetal heart rate. This specialized electrode is attached to the fetal scalp during labor, allowing for direct measurement of the electrical activity of the heart. By capturing these electrical signals, it ensures accurate monitoring of the fetal heart rate, which is critical for assessing the wellbeing of the fetus during labor.

This method provides advantages such as improved signal clarity and reliability compared to external monitoring methods, especially in cases where there may be interference or difficulty in obtaining clear signals through the abdominal wall. This capability is essential for timely interventions if any signs of fetal distress are detected, making continuous fetal heart rate monitoring crucial for both fetal and maternal outcomes during labor.
